Visual "Poke-in-the-eye" when loged in as siteadmin

If you are anything like me, you would like to have a poke-in-the-eye notification that you are currently logged in as a site admin. In my office, siteadmin doesn't contribute with content, just manages the creation of spaces, deleting trash and basic site setup tasks. In such case, some of use ... a double login. Our own login, and a siteadmin login. To help us prevent leaving content as a siteadmin we implemented this script to show us that we are loged in as site admin:

<script type="text/javascript">
<!--
/* HELPFUL FUNCTIONS */
function is_siteadmin () {
$item =  $('img#myareaavatarimg').closest('a');
return ($item.attr('rel').length - $item.attr('rel').lastIndexOf('siteadmin') == 9);
}

/* RUN MAIN FUNCTION */
$(document).ready(function () {
if (is_siteadmin ())
  {
    /*COLOR BACKGROUND TO DARK RED TO MAKE IT MORE VISIBLE A SITE ADMIN IS LOGGED IN*/
    $('body')
        .css('background-image','none')
        .css('background-color','#882222');
  }
});
-->
</script>

Just go to Site Settings as siteadmin and copy-paste the above code to your JavaScript for web statistics support section.

Just thought to share this with people that wanna have this :)
